Product Overview
Premium Silicon Bronze MIG Welding Wire engineered for precision joining of copper alloys, galvanized steel, and dissimilar metal combinations. This 1.2mm diameter, 13.6kg (30lb) spool delivers consistent arc performance, smooth feeding, and low spatter for professional fabricators, automotive restorers, and industrial welders.
Silicon bronze wire (commonly classified as ERCuSi-A) is prized for its low melting point, excellent corrosion resistance, and ability to produce strong, ductile welds with minimal heat distortion — making it a go-to choice for thin-gauge sheet metal, body panels, and braze-welding applications.
Key Features
- Diameter: 1.2mm (0.045") for versatile amperage range and stable arc control
- Spool Weight: 13.6kg (30lb) — extended run time, fewer spool changes, reduced downtime
- Alloy Composition: Copper-silicon alloy (ERCuSi-A) with excellent wetting characteristics
- Low Spatter, Low Fume: Cleaner welds, less post-weld cleanup
- Smooth Wire Feed: Precision-wound for consistent, tangle-free feeding through MIG guns
- Corrosion Resistant: Ideal for marine, plumbing, and outdoor fabrication environments
- Low Heat Input: Minimizes warping and burn-through on thin metals
Common Applications
- Braze welding galvanized steel (roof flashing, ductwork, sheet metal)
- Automotive body panel repair and restoration
- Joining copper, brass, and bronze components
- Silicon bronze to mild steel transition welds
- Marine hardware and plumbing fabrication
- Art metalwork and sculpture fabrication
- HVAC and sheet metal ductwork
